How to Build a Shipping Platform with EasyPost

EasyPost is a popular option for building a shipping platform because it offers multi-carrier rates, label generation, tracking, and pickup scheduling. This article explains how to design a shipping SaaS that uses EasyPost capabilities while keeping your architecture flexible for future carrier contracts.

Why EasyPost is different

Unlike some aggregators, EasyPost supports carrier pickup scheduling. That is a major workflow requirement for high-volume merchants who need daily pickups or time-window requests.

Core features to implement

• Rate shopping across carriers with markup rules
• Label generation and refund support
• Tracking status normalization and webhooks
• Pickup scheduling and pickup status tracking
• Address validation and corrections

Recommended architecture

Start with a clear separation between your public API and your carrier integration layer. This lets you swap or add carrier providers later without breaking customers. A typical structure looks like:

• API gateway: authentication, rate limits, versioning
• Carrier adapter: EasyPost client, error mapping, retries
• Shipment service: labels, documents, shipment lifecycle
• Tracking service: webhook verification, event storage, alerts
• Pickup service: pickup requests, status polling, cancellations

Data model essentials

• Account, API key, billing plan
• Shipment, parcel, label, rate quote
• Pickup request, pickup status, pickup window
• Tracking event, delivery confirmation

Carrier strategy

Even if you start with EasyPost, design your system so you can integrate direct carrier accounts later. This keeps your pricing flexible and avoids provider lock-in.
